This example demonstrates a candlestick chart.<br><br>
<ul><li> Create a candlestick layer using <a href="XYChart.addCandleStickLayer.htm">XYChart.addCandleStickLayer</a>.<br><br>
<li> Add custom text to the top left corner of the plot area using <a href="BaseChart.addText.htm">BaseChart.addText</a>.<br><br>
<li> Draw the y-axis on the right using <a href="XYChart.setYAxisOnRight.htm">XYChart.setYAxisOnRight</a>.<br><br>
<li> Rotate the x-axis labels by 45 degrees using <a href="TextBox.setFontAngle.htm">TextBox.setFontAngle</a> of the <a href="TextBox.htm">TextBox</a> object that represents the axis label prototype (returned from <a href="Axis.setLabels.htm">Axis.setLabels</a>).</ul>
